A cardiopulmonary resuscitation (CPR) device for performing automatic defibrillation and chest compressions on a patient and method for using same. The CPR device having a balloon configured to inflate/deflate, a belt configured to securely strap around a chest of a patient, a pair of electrode pads configured to deliver shock energy from a shock source, and, optionally, a pulse oximeter sensor. The CPR device is in electrical communication with a CPR defibrillator/ECG computer system that is configured to control the CPR device.

A chest compression device with a chest compression belt assembly including guards and sensors operable with a control system to control operation of the system depending on detection of proper installation of the guards.

A device for compressing the chest of a cardiac arrest victim.

Methods and apparatus for increasing cerebral blood flow for improving the flow of blood to the brain during and/or following an ischaemic stroke. The apparatus includes a plurality of inflatable cuffs to be positioned, in use, around a respective limb of a patient. Once inflated, the cuffs exert a pressure upon the limb to reduce blood flow to the limb below the point at which the cuff is positioned. Reducing blood flow to the limbs causes an increase in blood flow to the brain, and will therefore improve stroke outcomes. The apparatus includes a control module for controlling inflation and deflation of each cuff. The control module detects, measures and monitors cerebral blood flow and uses these measurements to control inflation and deflation of each cuff such that cerebral blood flow is maintained above a baseline level during treatment of the patient.

Processing generated sensor data of a mobile deep vein thrombosis (DVT) device may include identifying use of the mobile DVT device corresponding to a user. Sensor data associated with the user's identified use of the mobile DVT device may be generated. At least some of the generated sensor data may comprise ambulation data associated with a duration of ambulation during use of the mobile DVT device by the user. A protocol associated with ambulation of the mobile DVT device may be processed. The generated ambulation data and the protocol associated with ambulation during use of the mobile DVT device may be correlated. Based on correlating the generated ambulation data and the protocol, an alert associated with the generated ambulation data and the protocol may be generated.

Based on correlating the generated use data and the protocol, an alert associated with the generated use data and the protocol may be generated.

The present invention provides a limb compression device, including: a main body having a first surface where a support portion wrapping around a portion of a limb is provided, and a second surface where a fixing shaft fixing a cuff wrapping around a remaining portion of the limb is mounted; a drive motor coupled to the main body; a reduction gear unit coupled to a drive shaft of the drive motor; a cuff fixing drum fixing the cuff, and having a first end coupled to the reduction gear unit and a second end coupled to the main body such that the cuff fixing drum winds and unwinds the cuff; and the cuff including a first end fixed to the cuff fixing drum and a second end wound around the fixing shaft via the support portion of the main body so as to wrap around the remaining portion of the limb.

A compression device particularly suited for DVT prophylaxis includes a disposable wrap and a re-usable controller removably mounted on the wrap to apply a tensioning force to the wrap when it is encircling the limb of a patient. The wrap includes an RF chip with a unique identifier and the controller includes an RF sensor and processor to authenticate the wrap before commencing a compression cycle. A kiosk is provided for storing a plurality of wraps for use by patients and a plurality of controllers to be used with any of the wraps. The processor of each controller can control an electric motor in the controller to tighten and loosen the wrap according to a three-stage DVT prophylaxis protocol that produces an optimum blood flow velocity. An accelerometer and software/firmware in the controller can also measure and summarize patient activity while wearing the device.

In some embodiments, the present invention is directed to an exemplary inventive method having steps of: providing at least one housing having a pre-determined physical structure; fixing a first edge of at least one electro-active polymer (EAP) film within the at least one housing; connecting a first edge of at least one pulling mechanism to a second edge of the at least one EAP film; where a second edge of the at least one pulling mechanism extends outside of the at least one housing; sufficiently pulling at the second edge of the at least one pulling mechanism to form at least one pre-stretched EAP film that has been stretched in a first axial direction within the at least one housing by a first pre-determined, pre-stretched amount; and where the pre-determined, pre-stretched amount is limited by the pre-determined physical structure of the housing.

A gastrointestinal stimulation devices including a random stimulation delivery mechanism(s), configured to provide stimuli to a bodily tissue in a vicinity of the stimulation capsule, the provided random stimuli being characterized by a stimulation parameter, and a control circuitry in communication with said physical stimulation delivery mechanism, and configured to set and alter the stimulation parameter non-systematically, thereby altering the characterization of the stimuli provided to the bodily tissue. The algorithm may be patient tailored, and may have a learning machinery which responds to data being received from the patient.
